This was a great little app, but on the last update, the scroll inputs (from and choose input numbers) are now blank. The results still show but I have to blindly attempt to change the inputs until the output looks correct. It was 5 stars before before that (and it may work for you... but if you update the iOS, Apple purposely kills your battery life to get you to buy a newer phone).
This app is extremely helpful for homework and saves me from having to buy an expensive calculator! You are life saver!
Well designed & simple & easy to use. Big help with kids homework. Thanks!!
This application can calculate permutation and combination easily.
